IMPROVEMENT IN MACHINES FOR MAKING BRIDGE-EYES.

Specification forming part of Letters Patent No. 196,299, dated October 23, 1877; application filed August 2 5, 1877'.

To all euhom it may concern:

Be it known that 1, CHARLES KnLLoeG, of

I Buffalo, in the county of Erie and State of New York, have invented a new and valuable Improvement in Machines for Making Bridge- Eyes; and I do hereby declare that the fol.- lowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of referencemarked thereon.

Figure 1 of the drawings is a representation of a perspective view of my machine for making bridge-eyes; and Figs. 2, 3, 4, and 5 are details thereof.

The nature of my invention consists in the construction and arrangement of a machine for manufacturing eye-bars for bridges and other structures, as will be hereinafter more fully set forth.

The annexed drawing, to which reference is made, fully illustrates my invention.

A represents the frame of a steam-hammer, in which is a vertically-reciproeating hammer or ram, B. In the under side of the hammer B is secured the follower (3, of suitable shape for the purposes intended, by means of a dovetailed tenon a, and key I), as shown.

1) represents the anvil-block, upon which is secured the die-box E by means of a dovetailed tenon, e, and key (I, or by any other suitable means.

G and'G are the checks that formthe die in which the follower 0 works for forming the eye-bar. These checks are constructed substantially in the form shown, having their inner faces made concave at a, to form a cylinder when united together, and having the outer ends of their inner faces 5 made straight, so as to bear against the bridge eye-bar when the checks are closed, and hold it securely in position as the eye is being formed, and have at their inner ends rabbets '6 i, to fit under corresponding shoulders in the die-box, while at their outer ends they have hook-bolts h h, to fasten on the front end of the die-box.

The check or jaw G is stationary, and held in place by a dowel-pin, m, and the two checks are, at their inner ends, connected by a dowelpin, a, while the jaw G is movable, and held in place by a key, 19, as shown in Fig. 1 of the drawing.

The operation is to pile sufficient iron on the end ofa bar to form the eye or head, and when at a welding-heat the end of the bar, with the pile, is placed in the die formed by the cheeks or jaws G G. Then, by the action of the follower or drop O, the eye is formed of a shape according to the faces on the checks or jaws G G. While the eye is-being formed the other end of the bar is held against a stop that brings the bar to the required length.

When finished the key p is removed or moved back, which allows the jaw or check G of the die to move back, and the bar with the formed eye can be removed.

What I claim as new, and desire to secure by Letters Patent, is-- 1. The combination of the stationary cheek G and the movable cheek G, held to the diebox E by rabbets i t and hook-bolts h h, the dowel-pins m n, and key 19, substantially as and for the purposes herein set forth.

2. In a machine for manufacturing bridgeeyes, the combination of a drop, an anvil having a die-box, in which are a stationary cheek, G, and movable cheek, G, provided with the concavities r and straight portions 8, bearing against the sides of the blank when the bridgeeye is being formed, to hold it securely in position, the cheeks being held in the die-frame by a movable key, substantially as described, and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

CHARLES KELLOGG.
